LOUIS FESSMANN AND Gunman HAMM R'LE, or auesruae, amateur.

COMBINEDYABNGUIDING, CLEARING; AND mansion DEVICE.

To all whom it may concern:

Be' it known that we, Louis -FESSM A NIN,

a citizen of the German Empire, and Gun- HARD HAMM RLE, a citizen of the Empire of Austria-IrIungary, both residing at Augsburg, Germany, have invented certain improvements in combined yarn guiding, clearing, and tension devices, {such devices be-,

ing intended for use, more especially, in connection with mechanical warping-frames.

Our invention is especially designed to be employed-in a mechanical warping machine of a construction and. character de:

signed by us for use inwinding directly from the-spinning-frame bobbins on to the receiving beam in the former machine, and

by the use of which the usual-operation of winding from bobbins or cops upon sphols,

and the use of the ordinary creel for such spools at the time of unwinding from the s aidspools in a warping machine, are 'rendered unnecessary. Thereby much labor is saved, and much fioor. space is made available for other purposes. The manner of winding the cop and bobbins is not altered, nor is their shape changed at all,

I In the warping machine aforesaid we employ bobbin-supporting means providing for receiving reserve supply-bobbins or'cops,

which are groupedv closely 'with the one from which unwinding is actually proceed ing at any given moment, which'enables the inner end of the yarn-or thread on the'lat-' ter bobbin or cop to be joined, as. by tying, to the outer end of that of a second bobbin or cop, and so on throughout the group,

so that when the yarn or thread of one bobbin or cop becomes completely unwoundthe unwinding will immediately continue from the next bobbinor cop in turn, and-so that fresh bobbins or cops may be supplied as soon as the -previous ones havebecome eX 'hausted,' the unwinding operation thereby proceeding continuously and without interruption. Thereby the waste portions. of

yarns, Whichin the case'of other methods of unwinding liavehad to be left on the warping bobbins, and have added unnecessary weight, 1 are also obviated.

Briefly stated, the invention has relation to'devices for guiding the yarns so as to Specification of Letters Patent, Application file d October so, 1908. Serial No. 460,238. I,

facilitate the drawing-oft r. unwinding,

and, inaddition, clearing them of lintand foreign particles adherent thereto, and regulating the tension thereof.

The invention comprises novel and improved combined yarn-guiding,clearing and tension-regulating devices, and novel means ,of'providing'for the release and-discharge.

of accumulations of loose material atthe said devices.

\Vhile the features of .the invention are capable of being employed in connection with various kinds of machines, they have been designed more particularly for use in the bobbin frames or creels ,of warping ma chines.

The features, themselves, of the invention are illustrated in theaccompanying draw ings, which also indicate the application of such,features to a; bobbin-frame or creel.

In the drawnigs,-F1gure 1 shows in slde elevation a portion of thebobbin-frame or creel of a warping machine, and improved yarn-guiding,- etc., devices embodying the in-.

vention applied thereto. Fig. 2 is a view showing a portion of one ofthe horizontal rails-:01 channel-bars .of' Fig. '1 in longitudinal vertical section,'- and a combined guide, clearer, and tension" device applied thereto. Fig. is a view showing the parts of Fig. 2, mostly in vertical sectionin a transverse 'plane.- --'Fig. 4 is a plan view of a warping machine bobbin frame or creel.

(see Figs. 1, 2, 3) and uprights b, b. Thesaid rails or channel-bars aresupported one above another upon the said uprights. As indicated in Fig. 5, the arrangement of the 'horizontalrails or channel-bars and uprights is such as to produce in each, side of the warping frame or creel a number of compartments. As shown in Fig. 5, also, a pluralityof bobbin or cop-carriers is contained mechanlsm;

within each such compartment. The. two

sides of the warping frame or creel are joined together and the whole stiffened by cross-pieces b, b, 4. At d, d, Fig. 4,

are glass'rods carried by outstanding small brackets d, d, and around which the yarns change direction after leaving the guiding, clearing, etc., devices aforesaid; From said glass rods the yarns proceed to the winding The manner in which the yarn travels from the cops through the combined thread guide, clearer, and tension-device on its way to. the warping rollers can be seen from Figs. 1, 2 and 3'. u order to prevent the threadrubbing aga nst the rough iron parts and to prevent the numerous threads from colliding .with one another, they are led around the glass rods d just mentioned.

. Each of the horizontal rails or channelbars a, with the exception of the top one,

supports a series of bobbinor cop-carriers, and each thereof, with the exception of the bottom one, supports a series of the'combined guides, clearers, and tensiondevices.

These said devices are usually termedvalves or thread-valves in the art.

Each cop-carrier comprises a .base a and a series of bobbin or cop-receiving spindles f, Fig. 1. The said spindles are hinged orpivoted between pairs of upstanding lugs e on said base, so that a spindle may be swung the unwinding yarn or threa about its bobbin or cop. 'This capacity of downward and. outward, as represented at the right hand side of Fig. 1, into position to enable an empty bobbin or cop-tube to be removed therefrom anda full bobbin or cop to be applied thereto, without interfering with the other bobbins or cops, and, what is more important, without in rfering with as it circles the respective spindles to be swung outward for the purpose of supplying fresh bobbins or cops enables the bobbins or cops to be set more closely together upon the carrier, and to converge much more closely together at their upper. ends, than would be possible otherwise. It enables the bobbins or 0. ms to be brought more nearly in line with a line passing down I through the center of the delivery-guide above them, and renders it possible to locate the said guide a very short distance above the upper ends of the bobbins or cops. Thereby the extent of the ballooning of the unwinding yarn or thread as it circles around the bobbin or cop from which it is being drawn is very much reduced, which not only reduces liability to breaking of such yarn or thread,

but enables the carriers to be set closer to\ one another, thereby reducing the size of\ the bobbin or cop-supporting frame and consequently the extent of floor-space that is occuoied. 1

f, a'little yarn or thread is unwound from each cop and the inner end of'the yarn or thread of one cop is connected to the outer end of the yarn or thread of the next cop in the way hereinbefore mentioned. Before reaching the warping roller, the thread passes through the combined guide-,"learer, and tension device which is located immediately above the upper ends of the cops upon the spindles f, and is cleared as it passes th'rethrough, so that it reaches the warping roller perfectly clean and at the necessary tension.

The said combined uide, clearer, and tension device is mounterf upon the rail or channel-bar a next above that on which the copcarrier is mounted. It comprises essentially a seat orguide p in the form of a ring, and

a plate or disk m whi h rests upon the top ofthe said ring. Th yarn or thread unwinding from one of the bobbins or cops on the cop-carrier below passes up through the bore 0 of the rifig 7), and then turns, passing outward between the ring and plate or disk,

The latter rests by gravity upon the yarn, the friction due to thepassage of the yarn through the bore 0 of the ring, and to the bending of the yarn or thread nearly at right angles over the ring, as well as to the passage of the yarn or thread between the surfaces ofthe ring and plate or disk, imparting the required tension to the yarn or thread. As" the yarn or thread passes through .the device, loose particles are detached therefrom, the bore 0 of the ring permitting the said particles to fall away.-

The plate or disk m is connected loosely by a screw m with the lower.v end of a stem or pin Z, which occupies the central bore of .the

bushing and is movable vertically therein.

This provides for confining the said plate .or disk in'proper working position, while leaving it'free to be raisedby an operative as the latter introduces the yarn or threadbetween it and the top of thering, and also free to descend by gravity so as to rest upon the top'of the ring and the yarn or thread, and in addition permits it to accommodate itselfxto variations'in the thickness of th yarn or thread, or knot-s or loops. e The escape of. loose material which may be detached at the combined guide, etc., and which might tend to clog the device and pievent the plate for disk m from closing and acting properly,- is provided for in the following manner. .A slide-bar 70, Fig. 1, is

mounted'upon'one side-flange oft-he rail or channel -.bar by which the said combined guide, etc, is supported, and said slide bar is held to the said rail or channel-bar by means o f-s'crews k, k, the stems of which. occupy slots is, is, formed in the slide-bar .and-

extending .longitudinallyof the latter. This mode of connecting the slide to the rail or channel-bar provides for movement of the slide in the direction of its length. The

slide is formed or provided with an upwardly projecting nose or cam-portion 2' adjacent each combined guide, etc. -A horizontal pin 1* projects from upright stem or pin Z out through a vertical slot in the rail or channel-bar, and extends over the upper edge of the slide. Reciprocating movement imparted to the slide causes the nose or camportion ito pass back and forth beneath pin '1, thereby raising the pin 1", stem or pin Z,

and plate or disk mand leaving them free .to descend by gravity again. The slide at is connected in practice with means whereby Lt automatically is moved back and'forth every few seconds. Such means may be of any approved character. vHerein we have shown the slidek engaged with one'arm of a bell-crank 70 the other arm of which is engaged with a vertically-movable upright bar 70 Said bar is formed or provided at A its lower end" with a toothed rack. 70*, with which engages a spur-pinion 70 on a shaft k. Shaft is has,. in practice, a turning movement imparted thereto, first in one di- 46 nately raise and lower the bar Is -and this rection and thenin the other, so as to alter raising and lowering of the bar operates through the bell-crank k to communicate the required back and forth endwise moveruns on again under the correct. tension. The ring- 7) which has an oblique slot at for 'ment to the slide 7:. By this means the disk/m is raised sharply at intervals, so that the foreign bodies fall out and the thread admitting the thread into its bore 0, is pref- .erably constructed of glass as; are also the other parts used solely for guiding the thread. The ring p is held in a hook-shaped supporting clamp s, and can easily be removed and replaced by hand, which is also true of all the various parts. As can be seen from Fig- 3, the bushing 6 passes through a hole in the upper part of'the clamp s, and the latter is clamped by the flange of said bushing to the rail or channel- Y bar to which such bushing is applied.

A machine embodying the features herein shown and described does not require the weaving yarn to be spooled, but enables the yarn to be wound directly from the "cops on to the warping rollers, so thatit replaces the winding machines now in use,.which require so much attention, and in themselves reprcsent, a considerable amount of capital.

"\Ve do not lay claim herein to'the bobbin or cop-supporter, or to the feature of construction of the frame or creel, inasmuch as they are made the subjects of clalms 1n (l1V1-' of supply, and a surface across which said yarn or thread then travels, of a plate or disk mak ng contact with the said surface and pressing upon the said yarn or thread as the latter thus travels, and means for automatically separating said plate or disk and guide atintervals to permit escape of loose particles. 2. in yarn -del1ver1ng or unwmdmg devices, the combination with a leading-off guide having a passage fora yarn or. thread coming from a bobbin, cop, or other source of supply, and a surface 'across which the said yarn orthread then travels, of a plate or disk making contact.with the said surface and pressing upon the said yarn or thread as the latterthus travels, a cam-device operatively'connecting withsaid' plate or disk, and means for actuating said cam-deviceto automatically separate the plate or disk'and guidaat intervals to permit escape of loose particles.
